The Remington model 740 was the first semi-auto rifle chambered in 30-06,and was made from 1955-1959.The Remington model 742 was the next design and made from 1960-1980.I believe that the difference might be the gas piston,and the way the bolt locked up in the chamber(more bolt lugs).
Yes you can. I have shot some in my dads Rem 7400. If you do shoot it. treat it likes it is corrosive and clean the gun promptly and properly.
100-1000 USD and up depending on specifics
